Renewed July 15,'1935 1 Claim.

This invention appertains to new and useful improvements in washingmachine wringers, and more particularly to a safety attachment wherebythe likelihood. of injury occasioned by the oper- 5 ators fingers beingcaught between the rollers of the wringer, is substantially eliminated.

Another important object of the present invention is to provide a safetyattachment for wringers which can be readily applied to the conven- 10tional wringer assembly without altering the present construction.

Still another important object of the present invention is to provide asafety attachment for wringers wherein means is provided which will 15release the pressure roller of the wringer, and will also tend to urgethe hand away from the wringer rolls before the fingers are actuallycaught.

Other important objects and advantages of the 20 invention will becomeapparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of a conventional wringerassembly, showing the at- 25 tachment secured to the opposite sidethereof.

Figure 2 represents a horizontal sectional'view taken substantially online 2-2 of Figure 1.

Figure 3 represents a vertical sectional view through the attachment.

Figure 5 represents a fragmentary detailed sectional view takensubstantially on line 5-5 of 5 Figure 1.

Figure 6 represents a fragmentary detailed sectional view showing theadjustment for one of the riders.

Figure '7 represents a perspective view of the 40 horizontal connectingshaft.

Figure 8 represents a perspective view of the pressure roll releasinghandle engaging member.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Fig- 45 ure 1 that numeral 5 represents generally theconventional wringer which consists of a frame 6 in which is mounted theusual drive roll 1 and pressure roll 8. The pressure roll 8 has itsbear- 2 ing blocks engaged by an elongated strip spring 50 9 located inthe hinged, hollow upper portion In of the frame. The free end of thishinged portion I is secured to the frame proper 6 by a latch II and thislatch can be released by the handle l2. This construction isconventional 5 and now on the market. The spring 9 can be adjusted, asis well known, by a suitable screw I3 or other suitable means.

The attachment is generally referred to in Figures 3 and 4 by numeral l4and consists of an inverted U-shaped and substantially hollow frame 5l5, in the depending leg portions of which are the bearing blocks [6-46upon which the shaft ends of the lower fixed roll I! rests, while abovethe blocks l6-l6 are the blocks l|'l|, which have seats [8 therein forreceiving the shaft ends 10 of the upper mobile roll I9. A shoulder I9is provided at one side of the seat on each block 11 and this shoulderhas an overhanging portion 20 with respect to the shaft end 21 of theroll l9 so that in the event the roll I9 is forced upwardly, the shaftend 2| in riding against the over hanging shoulder portion will be movedin the direction of the arrow in Figure 5, that is, in the direction ofthe pressure roll 8 of the wringer.

Resting upon each of the shaft ends 2| is a 20 rider 22 which isprovided with a countersunk opening therein through which extends thethreaded barrel 23. A nut 24 is engageable on this threaded barrel andagainst the rider 22 to retain the barrel positively connected to therider. 25 The barrel 23 is internally threaded to receive the threadedend 25 of the rod 26 which extends upwardly and connects to thelaterally disposed arm 21 at the corresponding end of the shaft 28,which shaft is journaled through suitable bearing 30 elements 29. V

A bracket 3|] in the upper portion of the frame l5 rotatably supports amember 3| which is provided with a laterally disposed portion 32 havinga foot 33 engageable with the adjacent arm 21 of the shaft 28, while theopposite end of the member 3| is provided with an upwardly disposedportion 34 extending through an opening -35 in the upper portion of theframe I5 and an obliquely disposed extension 36 which is disposed 40over the handle I2 on the conventional wringer.

As is clearly shown in Figure 4, the upper mobile roll I9 is in closeproximity to the pressure roll 8 of the wringer. A suitable guide bar 31can be interposed between the drive roll 7 of the wringer and the fixedroll ll of the attachment so that material can be well guided toward thewringer rolls.

In operation of the attachment, material is fed between the rolls 11-19and permitted tobe caught between the wringer rolls. In the event, theoperators hand starts between the rolls l1 and I9, the upper roll l9,being free to rise, will be forced upwardly by the hand and in ridingagainst the overhanging shoulder portion 20, of

the bearing blocks H, the shaft ends 2| will cause the roller [8 to movetoward the pressure roll 8, and as the pressure roll 8 is moving in thedirection ofthe arrow in Figure 4, when the roll I9 engages the same,the roll I 9 will be driven in the opposite direction so that there is atendency of the roll Hi to force the hand out from between the rolls I'I-l9.

Simultaneously with this action of the roll IS, the rod 26 lifts, whileit rotates the shaft 28 and causes actuation of the member 3l, which inturn throws its extension 36 downwardly and exerts pressure against thehandle l2 so that the handle releases the catch II and permits thehinged section [0 of the wringer frame 6 to fly up, thus releasing thetension of the spring from the pressure roll 8.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter,

Having described the invention, what is claimed as new is:

In a wringer including a pressure roll and a drive roll and means forreleasing the pressure from the pressure roll; a pair of auxiliaryrolls, one of said rolls being an idler, the other roll being verticallymovable, guide means for moving the last mentioned roll toward thepressure roll to engage the latter when the former is moved vertically,and means engaged by the said vertically movable roll for actuating thesaid pressure releasing means of the pressure roll.
